Power up Your Equipment Conveniently with the 12v DC Power Supply
The 12v DC power supply unit powers up your DC equipment, such as LED light, directly from a 220v -240v mains power outlet. They are easy to operate and safe for use at home or the office. eBay stocks a variety of DC power supply units for different applications and price points.How does the power supply work?
The DC power supply comes with a rectifier and some diodes to convert the AC to DC. The power is first lowered to 12v and then converted to positive and negative flows at the rectifier. The negative diode allows negative current to pass to the negative terminal and closes off when positive power comes by. The same happens to the positive diode.Is the power supply safe to use at home?
Yes. All the circuits are enclosed in the casing, and there are no exposed wires. All you are required to do is to connect to the equipment you want to power up and plug into the power outlet. It also has inbuilt safety mechanisms to ensure a high level of safety so you stand no risk of electrocution.
